What is the objective of the study (as reported by the authors)? We performed a population-based study in Atahualpa, a village that is highly representative of rural coastal Ecuador, to assess the effects of total caffeine consumption on CVH status of stroke-free persons aged >/=40 years.

Provide a general description of the methods as reported by the authors. Information should be extracted based on relevance to the SR (i.e., caffeine related methods) This is a population-based, prospective cohort study, primarily designed to improve the CVH status and to reduce the burden of cardiovascular diseases in Native/Mestizos living in rural coastal Ecuador. Caffeine consumption was assessed with a questionnaire that inquired about the average number of cups/servings of coffee, tea, caffeine-containing soft drinks, and chocolate ingested per day, on the basis of the content of each of these products (http://www.energy- fiend.com/the-caffeine-database). Caffeine consumption was trichotomized in <100 mg/day, 100–200 mg/day, and >200 mg/day. The CVH status was evaluated with the seven metrics proposed by the American Heart Association, including: smoking status, body mass index (BMI), physical activity, diet, blood pressure, fasting glucose, and total cholesterol blood levels. Each of these metrics was categorized as "ideal," "intermediate," and "poor."

What were the listed confounders or modifying factors as stated by the authors? (e.g. multi-variable components of models.  Copy from methods) To recognize and exclude persons with stroke, all persons were screened by rural doctors with the use of a validated field questionnaire, and then certified neurologists evaluated suspected cases, as well as a random sample of negative individuals matched by age and sex for each positive case. We assessed the relationship between caffeine consumption and the CVH status and metrics of enrolled persons. Descriptive statistics were presented as means with standard deviations for continuous variables and as percentages for categorical variables. A generalized linear model was used to study the relationship between total caffeine and CVH status and metrics after adjusting for age and sex. A p value of less than 0.05 was considered significant.
